I understand your concern regarding the payments which are not received in full. Let me assist you.
On checking you account, I see that you account is in "Rolling sales reserve" which means "Out of country sellers with long ship times will be under 28 day rolling reserve in the first 120 days". So you will get the payments once in 28 days only.
In this case, I suggest you to contact the seller performance team and you can review your account.
So, I kindly request you to provide your justification to them and they will take necessary action.
Here is the email address to contact them:
